Re: Resume from ACPI S3 suspend breaks trackpad, mouse



The same thing happens to me (also on hibernating).
In addition I am running synaptics touchpad driver from
w1.894.telia.com/~u89404340/touchpad/
I tried to build the kernel from source applying patches for alps
touchpad provided by the kernel author, but they do not apply cleanly --
from looking at the source it appears most/some of them have been
implemented in the kernel.

Running with FC3 kernel -- no problems with suspend, hibernate (I am
guessing the same is true for vanilla kernel -- I did not build it, but
alps patches applied)
